- Контроллерди өз алдынча оңдоого же өзгөртүүгө аракет кылбаңыз. Тейлөө үчүн квалификациялуу адистерге кайрылыңыз.
4. Орнотуу жана орнотуу
4.1 Контроллерди орнотуу
Mount the charge controller vertically on a non-flammable surface in a dry, well-ventilated indoor location. Ensure there is sufficient clearance around the controller for heat dissipation. Use appropriate screws for mounting through the designated holes.
4.2 Зымдарды туташтыруу
Follow the connection order precisely to avoid damage to the controller or other components. The recommended cable cross-section is up to 4 mm².
- Батареяны туташтыруу: Connect the positive and negative terminals of the battery to the corresponding battery terminals on the charge controller. Ensure correct polarity. The controller will automatically detect the system voltage (12V же 24V).
- Күн панелин туташтыруу: Connect the positive and negative terminals of your solar panel(s) to the corresponding PV terminals on the charge controller. Ensure correct polarity.
- Туруктуу токтун жүктөмүн туташтырыңыз: Connect the positive and negative terminals of your DC load to the corresponding load terminals on the charge controller. Ensure correct polarity.
Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
